3 Claims.

This invention relates to circumcision clamps and more particularly to aclamp for substantially eliminating haemostasis incident to. acircumcision operation. i

It is among the objects of the invention to provide an improvedcircumcision clamp which is easy to apply and can be accurately adjustedto apply the proper pressure to a prepuce clamped therein to avoidhemorrhage upon severing of the prepuce without cutting or tearing ofthe prepuce by the clamp; which accurately centers the parts of theclamp to avoid the application of uneven pressure to a prepuce clampedtherein; which completely protects the glans penis during a circumcisionoperation and provides a firm guide for the operating knife or scalpel;which is easy to clean and maintain in a sterilized condition; and whichis simple and durable in construction, easy to use, and positive andeffective in use.

Other objects and advantages will become apparent from a considerationof the following description and the appended claims in conjunction withthe accompanying drawing wherein:

I Figure 1 is a perspective view of a circumcision clamp illustrative ofthe invention; and

Figure 2 is a cross sectional view on the line 2 -2 of Figure 1.

The clamp comprises a U-shaped frame, generally indicated at It,provided by a flat bar of elongated rectangular, cross sectional shapebent to form a substantially straight intermediate portion H and legs l2and I3 extendingsubstantially perpendicular from the same sideof theintermediate portion H, one at eachendofthe latter and disposed inspaced apart and substantially parallel relationship to each other.These legs are of substantially the same length, but the leg I2 isprovided at its distal end with a hinge butt formation M. Both legs arereduced in width by lateral cut outs, as indicated at l5, and the legsextend from one of the wider surfaces of the intermediate portion H.

The intermediate portion H is provided with a substantially centrallylocated hole I6 which tapers slightly in diameter from the side of theintermediate portion remote from the legs I2 and I3 to the side of theintermediate portion between these legs and provides a substantiallysharp angular or circular edge at its smaller end.

A flat lever I! has at one end a hinge formation l8 pivotally connectedto the hinge formation [4 of the leg [2 by a hinge pin l9 extendingthrough registering apertures in the hinge butt formations I4 and I8 andis provided at its other end with a notch 20.

A screw 2! is secured at one end to the leg l3 at the distal end of thisleg and projects longitudinally from the associated leg. This screw isreceived in the notch 20 of the lever H and a wing nut 22 is threadedonto the screw at the side of the lever ll remote from the intermediateportion ii of the frame in to force the lever l1 toward the intermediateportion of the frame.

A shank 23 is detachably mounted at one end on the lever I! by having anextension 24 of reduced diameter at one end thereof received in acentrally located aperture 25 in the lever with a precision fit. Theshank 23 extends perpendicularly from the lever ll toward theintermediate portion ii of the frame and has at its end remote from thelever ll a bell formation 26. This :bell formation has at its distal endan externally beveled annular surface 21, the smallest diameter ofwhich, at the extreme end of the bell formation, is smaller than thesmallest diameter of the tapered hole 55 and the largest diameter ofwhich is larger than the smallest diameter of the hole, so that thebeveled surface of the bell formation will not pass through the hole I6.Inwardly of the beveled annular surface 21 the bell formation isprovided with a complementary annular beveled surface 28, the twosurfaces providing a ridge of V-shape cross section extending around thedistal end of the bell formation 26. The bell formation includes acavity 29 of cylindrical shape having an inner end 39 of substantiallyhemispherical shape and a small aperture 3! extends through the wall ofthe bell formation near the adjacent end of the shank 23 to connect theinner end of the cavity 29 with the outer surface of the bell formation.

The hole It in the intermediate portion ll of the frame is of a sizesuch that a penis can'be drawn through this hole in the frame and willbe relatively closely surrounded by the edge at the smaller end of thehole. The cavity 29 in the bell formation 26 is of a size to closelyreceive the glans penis and the bell formation itself is of a size to beinserted in the prepuce.

I In the use of the device with the lever I! swung away from the bar l0and out of the way and with shank 23 and bell formation 26 detached fromlever H, the penis is drawn through the hole [6 in the intermediateportion of the frame and the glans penis is inserted into the cavity 29in the bell formation 26 and the prepuce is drawn over the outside ofthe bell formation. The distal end of the bell formation is theninserted in the hole It and lever I1 is then moved until the extension24 is received in aperture 25. The nut 22 is then placed on screw 2| andthreaded down against the adjacent surface of the lever to apply anaccurately controlled pressure to the portion of the prepuce between theedge of the hole 16 and the beveled surface 27 of the bell formation 26.When the proper pressure has been obtained, the prepuce is severed by aknife guided around the smaller end of the hole I6 on the correspondinginner surface of the intermediate portion H of the frame. With theproper pressure exerted by the clamp on the prepuce, no hemorrhage willoccur when the prepuce is thus severed. The clamp is left in place for afew minutes after the prepuce has been severed and when then removed, nohemorrhage will ordinarily occur, and the incision will heal rapidly andwithout complications.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is, therefore, to be considered in all respects asillustrative and not restrictive, the scope of the invention beingindicated by the appended claims rather than by the foregoingdescription, and all changes which come within the meaning and range ofequivalency of the claims are, therefore, intended to be embracedtherein.

What is claimed is:

l. A circumcision clamp comprising a. fiat U- shaped frame including anintermediate portion provided with a centrally located hole tapering toone side of said intermediate portion and legs of substantially the samelength and extending substantially perpendicularly from said one side ofsaid intermediate portion one at each end of the latter, one of saidlegs having a hinge butt formation at one end thereof, a flat leverhaving a length substantially equal to the distance between the distalends of said legs provided at one end with a hinge butt formationpivotally connected to the hinge butt formation on said one leg andhaving a notch in its other end, a screw secured at one end to the otherof said legs at the distal end thereof andextending longitudinallytherefrom for reception in the notch in said lever, a nut threaded onsaid screw and engageable with said lever at the side of the latterremote from said other leg for moving said lever toward the intermediateportion of said frame, and a shank detachably mounted at one end on saidlever at a location in alignment with the hole in said intermediateportion and extending substantially perpendicularly from said levertoward the intermediate portion of said frame, said shank having at itsend remote from said lever a bell formation having an externally beveledcircular end, the smaller diameter of which is less than the smallerdiameter of the tapered hole in the intermediate portion of said frameand the larger diameter of which is greater than the smaller diameter ofsaid hole and having an internal cavity of substantially cylindricalshape with a substantially hemispherical inner end connected by anaperture in said bell formation to the outer surface of the latter, the.hole in, said intermediate frame portion being of a size to receive apenis inserted therethrough, the cavity in said bell formation being ofa size to receive a glans penis and said bell formation being of a sizeto be inserted in a prepuce and clamp the latter between the beveled endsurface of said bell formation and the edge of said hole at the smallerend thereof.
